U.S. Pool Supply 6 Bottle Refill Solution Pack for Premium 5-Way Swimming

It works what else is there to say

This helps us keep our pool water clean.

Works as it should.

Exactly what I needed, I couldn’t find them locally.

Been using their products for a few years and all is well. Fast service and shipping.

I wish I could give it a 0. I also wish I had read the other 1 star reviews. It seems the product is ok for many people. However, for those of us unfortunate enough to purchase and have the chlorine drops work, you cannot return and get a refund. I would not chance this product if I was thinking about buying it. We shocked the pool, added extra chlorine tabs because it kept testing that we had no chlorine. We used someone else's kit and also had our pool guy come out to see what was wrong with the pool. Nothing wrong, chlorine fine (a little high at moment lol) it's these drops. Don't work. Bummer. Don't buy. Buy from someone else.

Good set

This is the easiest way to check our pool water! Great quality and works very well! In seconds we can tell if we need to add chlorine or PH (up or down). Must less expensive than the test strips!
